Viral suppression among South African patients on ART rose from 70 percent to 85 percent after viral load monitoring and adherence support were added. Retention in care reaches 78 percent at 12 months. Nearly half of those who remain unsuppressed are women.
Key Takeaways
- In South Africa, 49% of people with HIV who are not virally suppressed are women (sex-disaggregated UNAIDS/estimates context)
- In a South African cohort, viral suppression increased from 70% to 85% after implementation of viral load monitoring and adherence support (change over time)
- In South Africa, ART initiation within 30 days of diagnosis occurred for 62% of patients in 2019 (program cascade measure)
- South Africa achieved 78% retention in HIV care at 12 months for patients initiated on ART (cohort data)
- In a South African cohort study, 84% of ART patients were virally suppressed after 12 months
- Second-line ART costs are substantially higher: a 2019 South African costing analysis reported median second-line regimen costs about 2.5–3.5 times first-line costs
- A South African budget impact analysis estimated that dolutegravir rollout would avert costs from treatment failures and resistance management by approximately 10% over 5 years
- A 2021 study reported that 82% of ART patients in South Africa missed no appointments in the prior month (retention/adherence measure)
- A South African implementation study found community-based ART refills increased adherence by 12 percentage points compared with standard facility refills
- In a cohort study in South Africa, community health worker follow-up reduced loss to follow-up by 24% among ART clients
- About 30% of newly diagnosed people with HIV in South Africa have transmitted drug resistance to at least one antiretroviral drug class (surveillance estimate)
- In a South African trial, cabotegravir PrEP showed HIV prevention effectiveness of 0.0 infections among participants compared with expected background at study sites (trial interim results)
- In a South African evaluation, point-of-care CD4 testing improved linkage by 9 percentage points compared with centralized testing pathways
- In South Africa, lab turnaround time for HIV PCR results averaged 6 days after point-of-care or rapid transport interventions in 2020–2021 pilots
- Rapid HIV test positivity in key affected populations was 11.4% in a South African community survey (peer-reviewed study)
South Africa saw major gains in viral suppression and retention, alongside higher costs and ongoing resistance risks.

Second-line ART costs are substantially higher: a 2019 South African costing analysis reported median second-line regimen costs about 2.5–3.5 times first-line costs
02
A South African budget impact analysis estimated that dolutegravir rollout would avert costs from treatment failures and resistance management by approximately 10% over 5 years
Interpretation
Drug And Cost Drivers Interpretation
In South Africa, drug and cost pressures are evident because a 2019 costing analysis found median second-line ART regimen costs are about 2.5 to 3 times higher, and budget impact modeling for dolutegravir rollout indicates that preventing treatment failures and resistance management can help avert downstream costs, aligning directly with the Drug And Cost Drivers category.
